HVLS: Horizontal and Vertical Logic Scheduling for Multistory Projects
Publication: Journal of Construction Engineering and Management
Volume 120, Issue 4
Abstract
Multistory buildings are characterized by many repetitive units or typical floors, which involve identical activities repeated consecutively from one floor to the next. The scheduling of these activities is controlled by the logical sequence between activities executed on the same floor, horizontal logic, and between activities executed on different floors, vertical logic. Linear scheduling techniques have been developed for scheduling repetitive work in multistory projects. Although these techniques consider horizontal and vertical constraints in their scheduling approaches, they do not provide a formalized methodology for incorporating such constraints to generate schedules. This paper describes a structured procedure to incorporate horizontal and vertical constraints to schedule repetitive work. The procedure defines “critical floors” at which these constraints need to be checked to ensure that all other floors are satisfactory. The critical floors are grouped in a set of scheduling cases. For every activity, the procedure identifies applicable cases from the set of scheduling cases defined. To validate the constraints, the procedure only checks the critical floors defined in the selected scheduling cases and makes decisions to sequence activity.
